Unable to send mails from ePO

Hello ,

It seems my ePO can't send out emails anymore . Scheduled reports, manual reports export , etc ...nothing .

It worked just fine until a week ago , now it's dead :

Failed: Email File was unsuccessful due to an unknown error. The message could not be sent because of an unexpected error.

looked through AP logs to eliminate the obvious , no hits under the mass mailing block

Telnet on port 25 on the SMTP server works

Even checked the win event viewer logs ... all looking good .

any tips?

Re: Unable to send mails from ePO

are there a lot of unprozessed events under \db\events ?


dos a reboot of the epo give you same mail ? ( some short time)

Re: Unable to send mails from ePO

a restart of the ePO servies can fix it, but you should be looking in the ePO log files for the reason why it's not sending emails

Re: Unable to send mails from ePO

hello ,

i restarted the ePO processes good , I still get the same error .

The event folder has 2 sub folders :

Debug - filled with logs , but all that i randomly opened were related to malware or Gshield

Unknown - empty

next step would be rebooting the ePO ...but this needs to be coordinated .

Re: Unable to send mails from ePO

Could you make sure that ePO has access rights to your exhcange server (or servers)

Re: Unable to send mails from ePO

yeah ... on it (as it's not under my management) , but in the meantime i get another error

The message could not be sent because a connection could not be established with the SMTP server.

no idea what went on , but at least now I have something to start with ... prolly another CR went wrong ...

Re: Unable to send mails from ePO

I have the same problem here..

I have an client running epo server as stand alone 4.6.5 recently updated and i can't configure the server to send query results,  event notifications etc.

I justa wanna know how to trace this error, because the message given are not useful to debug this problem...

What i've done?

1- Checked if i can telnet the exchange server from the epo server, sucess.

2- Checked the email configuration from epo server, there a strange behavior.. when testing sending emails for a internal domain adress, it runs with sucess, but when i try to send for any external domains like gmail etc... it shows me " The message could not be sent because of an unexpected error.  "

3- Checked the acess protection policies of the virusscan on epo server.

4- Checked most logs on DB\logs\ nothing found.

5- Cheked the agent logs, nothing found

6- Checked acess protection logs.. nothing found.

My client checked the exchange and can't trace any problem from there on this service account, i need to show him at least a log with something useful to search a little bit more.

Any ideas?

Please under ePO server settings there is configuration for your exchange server and email id where ePO will send email, plz configure that.

2.If you have VSE installed then under antivirus standard protection ther is rule Prtect mass mailing worm from sending emails, exclude tomcat5.exe and tomcat7.exe (for epo 5.0) and aopply.

Also restart application se4rvice.
